I plan to brew a rye ipa this weekend and I am wondering how people are milling rye, as in gap setting. Seems as though it is pretty small and I can adjust my mill pretty far, any suggestions?
I ALWAYS see at least a 5% drop in efficiency when using a decent percentage of rye or wheat. Do you?That BrewTech is an awesome mill, would probably my choice too if I had to buy new.
Are you doing BIAB mashing?
FWIW, I use a converted cooler mash tun, with a slotted CPVC manifold on the bottom. Batch sparging 2x.
I've noticed crush quality and fineness is not all that important as long as it's crushed well.
Now with a large % of wheat and more so with rye, lautering is slow, agonizingly at times, even with ample rice hulls added.
Adding boiling water and lots of stirring helps to increase the flow.
No, I don't see a drop in efficiency, even at 50% of the grist.I ALWAYS see at least a 5% drop in efficiency when using a decent percentage of rye or wheat. Do you?
I think I'm crushing pretty fine, but maybe not fine enough. Gap is set to about a credit card width.
I do have a barley crusher as a backup mill now and maybe I'll plan to just use that for rye and wheat with the gap closed as tight as it will go. Not sure what that is.No, I don't see a drop in efficiency, even at 50% of the grist.
I do 2 equal volume (batch) sparges, though. The total amount of sparge water is the same as the mash, minus grist absorption.
A regular credit card would be around 0.034". That's a bit too wide for wheat and rye, at least on my 2-roller mill, they'd go mostly uncrushed.
Maybe try 0.022-0.025" and see if it improves?
Gap is set to about a credit card width.
Thanks for the info. I used to have some feeler gauges. I should pick up some new...On my Cereal Killer that's barley territory at an .032" gap. And your card could be way thicker than that.
I use my old Barley Crusher (with the reversed rollers) for oat malt, wheat malt, and rye malt with an .025" gap set.
btw, always use feeler gauges. I posted a survey of the ~10 cards in my wallet a month or two ago on a similar thread and there was a profound range of thicknesses...
Cheers!
Or use calipers and start measuring those credit cards and other thin flat plastic objects ...Thanks for the info. I used to have some feeler gauges. I should pick up some new...
